Hydrofluoric acid (HF) and Hydrogen Fluoride (HF) are very poisonous, highly irritating and corrosive. Hydrofluoric acid or Hydrogen Fluoride (HF) is fatal if inhaled, if swallowed, or in contact with ...

Atomic layer etching (ALE) is the reverse of atomic layer deposition (ALD). ALE can be achieved using sequential, self-limiting thermal reactions. We have recently demonstrated Al 2 O 3 ALE [1-3] and ...

Although chemists consider hydrofluoric acid (HF) to be a “weak” acid, its potential to produce serious health effects greatly exceeds that of “strong” acids commonly used in the laboratory. HF shares ...
